What 1946 speech by Winston Churchill used the term 'Iron Curtain'?

The 1946 speech by Winston Churchill that used the term “Iron Curtain” was the Iron Curtain speech.

Churchill delivered the address on March 5, 1946, at Westminster College in Fulton, Missouri. Its formal title was “The Sinews of Peace,” so it is also called the Fulton speech or the Sinews of Peace speech. Churchill warned that Soviet influence had divided postwar Europe, famously describing an “iron curtain” descending across the continent.

The speech became an important early statement of the tensions that developed into the Cold War. Churchill was not British prime minister when he delivered it; he was serving as Leader of the Opposition after the Conservatives lost the 1945 general election.

A common mix-up is confusing it with Churchill’s wartime speeches, including “Their Finest Hour” and “We Shall Fight on the Beaches.” Those speeches belong to World War II, while the Iron Curtain speech addressed the emerging division between the Soviet bloc and the West.
